What is silver impregnation, and how is it used in Cambridge Masks?
The Cambridge Masks utilize a process called silver impregnation to enhance their filtering capabilities.
How does silver impregnation work?
Silver impregnation starts with viscose rayon, the raw material for our carbon cloth. Viscose rayon offers superior filtration performance compared to granular or coconut-based carbon. This material is impregnated with silver before being processed through a double furnace system. During this heating process, the silver particles embed into the pores of the carbon cloth.
What happens after the silver impregnation?
The carbon cloth is then sealed with a protective layer of polypropylene (different from the melt-blown polypropylene in our middle-layer filter), which is laminated onto the fabric. This protective layer ensures that the silver remains securely within the fabric, preventing any loose particles from escaping. The laminated, shiny cloth you see on the inside of your mask is a result of this advanced process.
